Although this study found that exercise improves some aspects of cognitive performance, it also confirmed a recent meta-analysis in concluding that that folic acid supplementation does not significantly benefit cognition. A recent article by our group suggested that much of the relationship between folate levels and cognition may be attributed to exercise because exercise is known to raise folate levels. The current article further reinforces the need for research investigating the interaction of exercise, folate, and cognitive performance.
